 198 .SH CONFIGURATION
 199 .PP
 200 You can configure youtube\-dl by placing default arguments (such as
 201 \f[C]\-\-extract\-audio\ \-\-no\-mtime\f[] to always extract the audio
 202 and not copy the mtime) into \f[C]/etc/youtube\-dl.conf\f[] and/or
 203 \f[C]~/.config/youtube\-dl.conf\f[].
 204 .SH OUTPUT TEMPLATE
 205 .PP
 206 The \f[C]\-o\f[] option allows users to indicate a template for the
 207 output file names.
 208 The basic usage is not to set any template arguments when downloading a
 209 single file, like in
 210 \f[C]youtube\-dl\ \-o\ funny_video.flv\ "http://some/video"\f[].
 211 However, it may contain special sequences that will be replaced when
 212 downloading each video.
 213 The special sequences have the format \f[C]%(NAME)s\f[].
 214 To clarify, that is a percent symbol followed by a name in parenthesis,
 215 followed by a lowercase S.
 216 Allowed names are:
 217 .IP \[bu] 2
 218 \f[C]id\f[]: The sequence will be replaced by the video identifier.
 219 .IP \[bu] 2
 220 \f[C]url\f[]: The sequence will be replaced by the video URL.
 221 .IP \[bu] 2
 222 \f[C]uploader\f[]: The sequence will be replaced by the nickname of the
 223 person who uploaded the video.
 224 .IP \[bu] 2
 225 \f[C]upload_date\f[]: The sequence will be replaced by the upload date
 226 in YYYYMMDD format.
 227 .IP \[bu] 2
 228 \f[C]title\f[]: The sequence will be replaced by the video title.
 229 .IP \[bu] 2
 230 \f[C]ext\f[]: The sequence will be replaced by the appropriate extension
 231 (like flv or mp4).
 232 .IP \[bu] 2
 233 \f[C]epoch\f[]: The sequence will be replaced by the Unix epoch when
 234 creating the file.
 235 .IP \[bu] 2
 236 \f[C]autonumber\f[]: The sequence will be replaced by a five\-digit
 237 number that will be increased with each download, starting at zero.
 238 .IP \[bu] 2
 239 \f[C]playlist\f[]: The name or the id of the playlist that contains the
 240 video.
 241 .IP \[bu] 2
 242 \f[C]playlist_index\f[]: The index of the video in the playlist, a
 243 five\-digit number.
 244 .PP
 245 The current default template is \f[C]%(title)s\-%(id)s.%(ext)s\f[].
 246 .PP
 247 In some cases, you don\[aq]t want special characters such as 中, spaces,
 248 or &, such as when transferring the downloaded filename to a Windows
 249 system or the filename through an 8bit\-unsafe channel.
 250 In these cases, add the \f[C]\-\-restrict\-filenames\f[] flag to get a
 251 shorter title:

 281 .SH FAQ
 282 .SS Can you please put the \-b option back?
 283 .PP
 284 Most people asking this question are not aware that youtube\-dl now
 285 defaults to downloading the highest available quality as reported by
 286 YouTube, which will be 1080p or 720p in some cases, so you no longer
 287 need the \f[C]\-b\f[] option.
 288 For some specific videos, maybe YouTube does not report them to be
 289 available in a specific high quality format you\[aq]re interested in.
 290 In that case, simply request it with the \f[C]\-f\f[] option and
 291 youtube\-dl will try to download it.
 292 .SS I get HTTP error 402 when trying to download a video. What\[aq]s
 293 this?
 294 .PP
 295 Apparently YouTube requires you to pass a CAPTCHA test if you download
 296 too much.
 297 We\[aq]re considering to provide a way to let you solve the
 298 CAPTCHA (https://github.com/rg3/youtube-dl/issues/154), but at the
 299 moment, your best course of action is pointing a webbrowser to the
 300 youtube URL, solving the CAPTCHA, and restart youtube\-dl.
 301 .SS I have downloaded a video but how can I play it?
 302 .PP
 303 Once the video is fully downloaded, use any video player, such as
 304 vlc (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).
 305 .SS The links provided by youtube\-dl \-g are not working anymore
 306 .PP
 307 The URLs youtube\-dl outputs require the downloader to have the correct
 308 cookies.
 309 Use the \f[C]\-\-cookies\f[] option to write the required cookies into a
 310 file, and advise your downloader to read cookies from that file.
 311 Some sites also require a common user agent to be used, use
 312 \f[C]\-\-dump\-user\-agent\f[] to see the one in use by youtube\-dl.
 313 .SS ERROR: no fmt_url_map or conn information found in video info
 314 .PP
 315 youtube has switched to a new video info format in July 2011 which is
 316 not supported by old versions of youtube\-dl.

 338 Since June 2012 (#342) youtube\-dl is packed as an executable zipfile,
 339 simply unzip it (might need renaming to \f[C]youtube\-dl.zip\f[] first
 340 on some systems) or clone the git repository, as laid out above.
 341 If you modify the code, you can run it by executing the
 342 \f[C]__main__.py\f[] file.
 343 To recompile the executable, run \f[C]make\ youtube\-dl\f[].

 365 A common mistake is not to escape the \f[C]&\f[].
